The idea for Java Argument Validation came from a project on which arguments where not checked. The test department
run some tests and several times they came with issues, that something wasn't working, Which then after some
investigation wasn't the case, because they had provided incorrect or to few parameters. Or the provided
values where incorrect. Yes, you're right, the test specifications should have been better. Correct! But the same
was true for the 'use cases', 'User stories' or 'functional specification'. This solution made that application
more robust and far more clear for the testers. As it provide fast and good feedback about what was wrong, with the
parameters they used.

There are several small validation packages out there, but they all seam to concentrate around,
web application user input validation. Several other are about checking command line arguments.
Therefore I continued to work on the project specific solution.
After a while I realized that the class
ArgumentValidation
got quite some nice features, which made me decide to extract it from the main project.
Cleanup it up adding some missing parts of the java documentation and publish it on
SourceForge.net.

how it is used.
